Inventor: JOHNSON JAMES R
IPC: B31B19/90
Filed: 1988-04-12
Abstract: A method and apparatus for forming draw tape bags wherein the bag material moves continuously during the manufacture, except for the last step. The apparatus may be used with an in-line system wherein a tube (21) is extruded and a side gusset is formed to create a hem; or the apparatus may be used with an off-line system wherein folded bag material (54) is used, and a continuous hemmer is provided to turn the loose edges. In the off-line system a constant tension dancer (56) precedes the hemmer (59) to maintain constant tension on the web regardless of the size of the supply roll. The web continues to move, and a cutter (60) is actuated to move through a circle and engage the web to punch finger holes in the hem. A reel (36) of a strip of material is continuously fed, the strip being slit longitudinally to provide the draw tapes which are inserted into the hems. A tape guide (41) tensions the tape and assures that the tape is well within the hem, the hems are sealed, and the bags are side welded.

Abstract: An apparatus and method for aiming vehicle headlights and for visually displaying the illumination patterns of vehicle headlights. The apparatus focuses the light beam on a screen (12) and includes a video sensor (13) for sensing the intensity of the light in each cell of a matrix of cells overlying the focused light beam and for generating an electrical signal for each cell indicative of the position of the cell and the intensity of the light beam in each cell and a computer for comparing at least some of the electrical signals to each other and with established criteria to determine whether the headlight is aimed within a prescribed degree of accuracy. The same apparatus may be used to describe the illumination pattern of a headlight by visually displaying at least some of the electrical signals, i.e. the light intensities and their locations, for example on a printer or CRT. The conformance of headlight aiming and illumination to established standards can be easily determined by including steps in the computer software to apply the applicable criteria. The aiming conformance tests may produce error signals for controlling powered screwdrivers to correct errors in aiming. The apparatus preferably includes a centering indicator for centering the headlight relative to the lens by comparing electrical signals produced by discrete light intensity sensors (14) disposed around the periphery of the lens.

Abstract: An apparatus for continuously producing from liquid and powder ingredients a substantially homogenous mixture and kneading the mixture to form a compact, plastic mass, and for extruding this mass into elongated extrusions. The mixer comprises a mixer housing (1) and mutually separate liquid and powder delivery conduits (18, 19) and a mixture outlet. A wheel assembly (3, 4) is arranged for rotation in the housing (1) on a shaft (5). The liquid delivery con­duit (9) opens into a cavity (7) located in the wheel assembly, whereas the powder delivery conduit (18) opens into powder spaces (10) provided in the upper part (3) of the wheel assembly. The cavity (7) communicates with the upper side of the wheel assembly via a circumferentially extending slot or gap (8) which opens out adjacent an edge (11) which extends circumferentially around the slot or gap on the peripheral side thereof. The slot has a substantially frusto-conical configuration with the apex of the cone facing downwards. Extending around the periphery of the mixer hous­ing is a cylindrical shell (15) which is perforated with holes (16) in that part thereof which extends over the housing outlet, the axes of this shell being coaxial with the axes (5) of the mixer wheel. Blades (12) are arranged in the chordal direction in the mixer housing between the cir­cumferentially extending edge (11) and the cylindrical shell (15). The edges (13 of the blades (12) lie immediately adjacent the inner conical surface (14) of the mixer housing and knead and tear the mixture in co-action with the surface, while the outer ends (21) of the blades lie against the inner surface (22) of the shell (15) and are operative in forcing the resultant plastic mass through holes (16) to produce elongated extrusions.

Abstract: PCT No. PCT/FR88/00005 Sec. 371 Date Nov. 1, 1988 Sec. 102(e) Date Nov. 1, 1988 PCT Filed Jan. 5, 1988 PCT Pub. No. WO88/05118 PCT Pub. Date Jul. 14, 1988.The present invention provides an improved rotary machine of the type having male and female rotors with complementary intermeshing helical teeth. The improvement relates to the profile of the teeth, particularly the teeth of the male rotor, so that there is a reduction of the phenomenon of wedging of the sealing, lubricating or cooling liquid molecules and a reduction of the wedging of the molecules of gaseous fluid between the bores and apices of the teeth. The improved profile of the teeth and the resulting reduction of the wedging phenomenon prevents a loss of power which is typical in the prior art screw-type rotary machines.

Abstract: Dans le procédé et le dispositif décrits, le débit de carburant dans la plage de charge partielle est dérivé de diagrammes caractéristiques multidimensionnels, tandis que dans la plage de pleine charge, le débit de carburant est limité au moyen d'une régulation lambda. On utilise des incréments de sélection de valeurs minimales pour délimiter les diverses méthodes de régulation du débit de carburant. En dépit de temps de retard inhérents au système, on obtient un système de régulation lambda dynamique et satisfaisant, puisqu'on utilise une commande rapide jusqu'à une courbe d'intersection, et ensuite la régulation lambda plus lente. Par suite de la mise en oeuvre d'une régulation lambda pour limiter la pleine charge, les gaz d'échappement sont pratiquement exempts de particules.

Title: Rotary piston compressed air motor.
Inventor: LUTZ GERHARD
IPC: F01C13/02
Filed: 1988-11-19
Abstract: A rotary piston compressed air motor has a housing (1) in which is lodged a rotor (3) whose drive shaft (44, 45) emerges from the housing through a passage (48) protected from explosions in order to drive any type of unit, for example a pump. The gap (50) between the drive shaft (44, 45) and the passage (48) in the housing is designed to preclude the emergence of ignition sparks. The motor housing (1) has a pressure-proof protection. An ignition spark barrier (28) made of sintered metal is arranged in the compressed air suppy line (7) and in the exhaust air line (37). All the threaded connections (23, 27) for fastening the ignition spark barriers (28), both in the compressed air supply line (7) and in the exhaust air line (37), prevent the passage of ignition sparks. The same applies to the threaded connections (49) between the passage (48) in the housing (1) and the part (2) of the housing (1), the threaded connection (39) between the exhaust air line (37) and the shoulder (38) of the part (2) of the housing, and the threaded connection (10) between the valve (8) and the housing bore (9).

Abstract: Certain articles required to function in air at temperatures of 250°C or higher comprise very fine particles of vermiculite from which the interstitial magnesium ions have been at least partially removed and which has been swollen in water. These articles are not ordinarily exposed to water when in use, but if they are they are likely to disintegrate quickly because of the ready dispersibility of the vermiculite particles. By the invention, water-resistance is given to such articles by treating them with a solution of an aluminate salt eg NaAlO₂ or a zirconyl salt eg ZrOCl₂.

Abstract: According to the invention, in the drum, the axis of which runs horizontally or at a slight incline, a sliding member is arranged, which is axially movable independently or by means of additional drive means and which, during the rotary movement of the drum, bears with its external surface against the settlings or against the internal surface of the drum. The sliding member has an approximately elliptical cross-section of the three-centre curve type, and, resting with its larger curved external surface in the drum, is, upon its rotation, taken into a position raised from the bottom position. After the static friction limit value has been exceeded, the sliding member slides back into the bottom position, positioning itself axially, the settlings being removed completely or in layers, against the rotary movement of the drum, by means of working elements which scrape and rub.
